BRONZING-MACHINE.

Application filed, March 21,' 1907. Serial No. 363,733.

fo all whom it may concern:

Be it known that I, WILLIAM E. HoUGH- LAND, of Brooklyn, in the county of Kings, and in the State of New York, have invented a certain newpand useful Improvement in Bronzing-Machines, andl do hereby declare that the following 1s a full, clear, and exact. description thereof, reference being had to the accompanying drawings, inv which- Figure 1 is a left side elevation of a machine embodying my invention; Fig. 2 is a right side elevation of Fig. 1; Figs. 3 and 4 are respectively front and rear elevations; Fig. 5 is a top plan View; Fig. 6 is a vertical cross sectional View; Fig. 7 is a top plan view of a portion of a magazine, and Figs. 8 and 9 are sectional views taken on the lines 8-8 and 9-9 of Fig. 7, and Fig. 10 is a fragmentary erspectiveview showing one of the edges o the paper to prevent the brushes from catching on such edges.

The object of my invention has been to provide an efficient machine for automat; ically applying bronze powder, or other similar powder, to paper, cloth, or any other material which has been previously coated partially o1' wholly, or which has been previously printed upon with an adhesive ink or size, and for dusting and polishing said paper. And to such ends my invention consists in the bronzing machine hereinafter In carrying my invention into practice, I provide a table 1() that may be supported by leg-frames 11. On the upperl surface of the table are bolted end-frames 12 and 13 respectively, to which most of the operative parts of the machine are secured.

The machine is designed to bronze paper in a fiat position. At the front of the machine is a table 14 upon which the paper to be bronzed is placed. A shaft 15 is journaled in the supports of the table 14, and a shaft 16 is journaled in the end-frames of the machine, each of such shafts having pulleys 17 mounted thereon, over which run feedbelts 18, that are adapted to carry the paper into the machine. The said belts are driven b being compressed between the pulleys 1 and a roller 19, that is also journaled in the end-frames of the machine. The paper is held down upon the roller 19 by rollers 2O on a shaft 21, said shaft beinv' pressed down by spring-arms 22. AThe shaffI 21 and the shaft of the roller L19 are geared lates 'or extending over the sideV Specication of Letters Patent. Pate-ni-,d 1)@121 1909.

together, and the teeth are of suiicient depth. f 'l i so that the rising and falling of the rollers 2O willnot wholly disengage said gears.

Above the belts 18 is a lower magazine consisting of a front-wall 23, and a. rearwall 24, and a bottom consisting of a. wiremesh 25, beneathwhich is a sheet of 'metal 26 havingV slotsk 27 formed at intervals. r Beneath the bottom of the hopper are secured cleats 28 and 29 that between them hold shdes 30, which can be drawn'back vto permlt bronze to fall from the slots 27, or which can be forced forward to the position shown in Fig. 8, in which bronze will be prevented from falling. Within the lower ma azine is a block 31 having an inclined frontace that forces the bronze over the slots 27. Within the lower hopper is a bar 32 that is supported as by a plate k33, sliding on the wall 23 of the lower hopper. l Brushes34 are se-V cured in the bar 32 and extend down tothe wire-mesh.- A barf35 is secured to" the plate 33 outside theflowerhoppe'nsaid bar being provided with afplate 36fhaving' slots in which are mounted rollers 37 j' that are secured to thev wall ofthehopperby screws 38, so as to form guides for the bar 35. The

plate 36 is reciprocated by a connect-ingrodl 39, which, (see 'Fig. 5) is attached to a crank-pin 40 on a gear 41 that meshes with a pinion on a shaft 42, the latter being provided with a gear 43 meshing with a gear 44 on a shaft 46. The shaft 46 has a sprocketwheel 47 that is connected by a chain 48 with a sprocket-wheel 49 on the driving-shaft 50.

Bronze is .supplied to the lower hopper from upper hoppers consisting of cylindrical receptacles 51 mounted upon rectangu lar bases 52 that are adapted torest vupon flanges 53, which latter are secured to the under-sides of bars 54. The bars 54 are connected at their ends by plates 54, which springing said bars together, and clamping the bases of the receptacles. Each receptacle 51 has a pipe 57 extending down and into the lower hopper. Each receptacle 51 has a vertical shaft 58 that is journaled in the base 52, and in a bar 59 secured across tlie'upper end of the'receptacle. Each shaft 58 hasva ratchet-wheel 60 on its lower` end,

'said levers shall move in unison.

beneath the base 52. Within eachreceptacle 51 the shaft 58l carries 'a brush 61. In order to rotate the brushes a bar 62 is slidably mountedl in the frame and is providedv with spring-fingers, or pawls 63 that are adapted to engage the ratchet-wheels on a rlght-hand stroke, as seen in Fig. 5, and to spring past such wheels on the return stroke. The bar 54 is drawn to the left, as seen in Fig. 5, by a spring 64 (Fig. 6), and it is dra-Wn to the right, as seen in Fig. 5, by a cord 65 secured to a hook 66 on the bar, and passing around a pulleyl 67. The cord 65 is secured to a connecting-rod 68, lto be later described. Any desired number of receptacles 51 can be used at a givenvtime.

After having received bronze vfromthe lower magazine, the paper passes over a fixed wire-mesh 69, whichsupports the paper beneath pads 70 that areadapted to rub the bronze evenly over the' paper. Each pad 70 1s supported on a lever 71 that is pivoted at 72 on the under-side of a bar l"(3, the latter being secured to the side-bars 74 of an oscillating frame, said frame beine*v pivoted on a shaft 75 mounted in the end-iframes of the machine. The rear ends of the lever 71 are pivoted to a -bar 76, toinsure that I At fl point between the pivot 72 and the brushes, the levers are pivoted to a bar 77, which has a bracket 78, to which are pivoted connecting-rods 79, each of said rods being pivoted to a crank-pin 80 on a shaft 81 that is journaled on the pivoted frame before referred to. The shafts 81 have bevel gears 82 which mesh with bevel gears 83 on the shaft 75. The latter shaft has a bevel gear 84 that meshes with a similar gear 85 loose on the shaft 42 before mentioned. The side-bars 74 of the pivoted frame carry at their rear ends a counter-weight which may be conveniently formed of a pipe 86 mounted on heads 87 on a rod 88 that is secured in the said side-bars. In order to prevent the pads 70 from catching on the side edges of the paper, the paper is protected by plates 150 that are adjustably securedf to the bars supporting the netting 69 by a thumb screw 151, which engages a flange or blade depending from the plate 150, the screw passing through a horizontal slot. There are two y plates 150, one for each of the side edges of the paper. plates 150 to be adjusted to suit the width of the paper being worked upon. yThe frame the side-bars 74, and with it the pads 70,'

'A is raised away from the paper whenever the paper is fed. In order to raise such frame, the said side-bars are connected by a connecting-rod 89 with an apron 90 pivoted on a shaft 91 secured in the end-frames, and the said apron is oscillated on the shaft 91 by a connecting-rod 92, connecting the `apron withl a crankfpin 93 ona. shaft94 mounted 'terial that This construction enables the-- `antw; n'

lin the end-frames. The apron 90 has a Wiremesh 95 that is supported above the apron by strips 96, so that-th'ener portions of the bronze falls through the said mesh and lonto the apron, while the larger particles are caught b the mesh, and-fall down against a vertica portion 97 of the apron.l The maasses through the` wiremesh 95 drops o the end of the apron int'o a receptacle 98 having a bottom slanting down to a chute 99 that is closed by a valve having a handle 100. Within the receptacle 98 is a pivoted bottom 101, pivoted at its end remote from the chute, its end nearer the chute being connected by a rod 102 with the apron 90, so that said pivoted bottom is oscillated with the apron, and tends to feed the bronze into the chute 98. The apron 90 is`provided with a counter-weight 103, similar to that of the side-bars 74.

Beyond the wire-mesh 69 the paper is fed between a lower shaft 104, similar to the shaft 19, and rollers 105, of an upper shaft 106, similar to the shaft 21. |The paper next passes over a wire-mesh 107, supported on bars 108, extending between the end-frames ofthe machine. While the paper is supported on .the wire-mesh 107, the excess bronze is brushed oft' by narrower and Wider brush-belts 109 and 110, respectively, such belts being mounted on pulleys on shafts 111 that are -journaled in cross-bars 112 and 113 respectively, of a -frame which is pivoted on a shaft 114 mounted in the end-frames, the said pivoted frame having a counterweight 115, similar. to that of the frame of the side-bars 74. The end pulleys of the series over which the brush-belts run should be crowned to keep thebelts in place, while the intermediate pulleys may be cylindrical. The right and left shafts 111 are each provided with bevel gears 116 that mesh with' bevel gears 117 on the shaft 114, the gears being so arranged that the under-surfaces of the belts travel from the centerof the paper toward the sidev edges thereof, thus avoiding any tendency to catch on the side edges, and muss the paper. The parting between the two belts 109 occurs between a *different pair of the pulleys from that of the two belts 110, and thus the portion of the paper not brushed at the lparting of the belts 109 is brushed by the left hand belt 110, and the portion that would not bebrushed at the parting of the belts 110, is brushed by the right hand belt 109. The belts 110 are wider than the belts 109, so that for any feed less than the width of the belts 110, the portion of the paper between the belts 109 and the belts 110, and, therefore, unbrushed` will,upon the next feed, be brushed by the belts 110. The frame 112 is oscillated to raise the belts oil" the paper at each feed by connecting-rods 118, connecting the side-bars of the -said frame with an apron 90. Thel a er, after assing beneath the brushinge ts, is fed a ong by pulleys 119 and a shaft 120, similar to the said pulleys and shaft before referred to, and it passes over a belt '121 that runs over shafts 122 and 123 extending between the side-frames, continuousl and at the same speed as the feed, and the atter belt serves to brush 0H the bronze from the under-side of the paper, the "belt itself being cleaned by running over a wire-mesh 124, supported by the frame. The shafts 122 and" 123 each carry a gear meshing with an idler 125, so that the two shafts will turn in the same direction. Fixed guide-plates 121a serve. tolhold the paper down on the belt 121.

Motion is'transmitted to the parts not already described as follows: As before stated, the driving shaft transmits motion to the shaft 46 by the chain and sprocket gearing. The shaft 46 has a' gear 126 meshing with an idler 1,27 that drives a gear 128 which is movable on the shaft 42. The late ter gear is connected with the bevel gear 84 s' before mentioned. The shaft 46 has a bevel gear 129 meshing with a similar gear 130 on the shaft 114 before` mentioned. The shaft 114 carries a pinion 131 meshing with a gear 132 on a shaft 133, the latter shaft having on its end a crank 134, whose crank- 'pin is adjustable in a slot in said crank, to

vary the throw of the crank-pin.. The connecting-rod 68, before mentioned, is oo nnected with said lcrank-pin. The opposlte end of the said connecting-rod oscillates a pawl-lever 135, the pawl of which engages a gear 136 from which the feed is driven. The gear 136 meshes with gears 137 and 138 that are respectively on the shafts 106 and 21, carrying feed-rollers before mentioned. The shafts 104 and 19 have pinions that respectively mesh with the gears 137 and 138. Motion is transmitted from the gear 137 b v an idler 139 toa gear 140 on the shaft 119a of the saidrollers 119. The

shaft 120 has a pinion 141 meshing with the gear 140. A crank 142 is secured on the shaft 21, so that, upon releasing the pawl, the feed mechanism can be workedlby hand. The shaft 133 has a sprocket 143, which,

through a chain 14.4, turns a sprocket 145 on the shaft 122, before described.

In' the operation of my machine, the paper is rst printed on or coated partially or fullywith an adhesive ink or size The feed-rollers 20, 105 and 119, which are rubber and are adjustably secured to their shafts as by set-screws, are adjusted, so that they willengage the edges of the paper, but will not engage the paper Where the bronze is to be applied. These rollers can be readily gotten at by disengaging thel connectingrods from'the pivoted frames, and raising such frames entirely out of the Way. This ability to raise the frames out of the way is also a great advantage in cleaning the machine. vThe, paper is then laid on the belts 18 and engaged with the first feed-rollers. The maelnne is set in motion, causing the brushes 6l to rotate in the cups 51, and to brush some of the bronze or other powder into the tubes 57, from whence it flows into the lower magazine. ln the lower magazine the bronze is brushed back and forth over the Wire mesh by the brushes 34, and sifts through such mesh at the slots 27, falling upon the paper in a shower, which causes the bronze to be well scattered over the paper. The reciproeation of the connectingrods cause the feed-rollers to be rotated a step, and moves the )aper forward under the pads 70. l'At the tlme of the said movement, the pivoted frame carrying the pads is raised so that the said pads do not catch the front edge of the paper. These pads rub the bronze thoroughly and evenly into the sizing, and thus cause a design to appear upon the paper in bronze, corresponding to what has been printed upon it in size These operations continue until the paper has arrived under the brushingbelts 109 and 110. These belts take off all loose bronze which has fallen where there is no sizing, or which has not adhered to the sizing, the lexcess thus removed and the bronze scattered by the brushes 70 falling upon the apron 90 and being carried into the receptacle 98. As before described, the belts 109 and 110 brush -from the center of the paper outward, so that they run over the edge of the paper, instead of on to it,

and thus they avoid catching and mussing the paper. It has also before been explained how the width of the brushing-belts is so proportioned to the feed motion, that the portion of the paper not brushed because it stops between the belts 109 and 110, is brushed' at the end of the neXt step. During the feed motion, the brush-belts are raised out of the way, so that the front edge of the paper does not catch under them. After reaching the brush-belts, the paper passes under the guide plates 1213, and the belt 121 cleans the under-side of the paper of bronze when the paper is stationary. When there is no paper in the machine, lthe pads 70 clean themselves on the Wire fabric 69; the brush-belts 109 and 110 clean themselves on the wire fabric 10T, and the belt 121 cleans itself on the wire fabric 124. By regulating the length of the feed step, as many applications of the pads or brush-belts as may be desired can be given to the said surface.

Adjustable plates may be provided to protect the side-edges of the paper, Where the pads 70 sweep back and forth, so thatl such edges will not be caught by said brushes.
